我的驅動器是否出現故障，這是否與我的筆記型電腦執行速度較慢的原因相同？

我執行 Ubuntu-20 並使用smartctl掃描了我的筆記型電腦。測試結果如下：

我的驅動器出現故障了嗎？我正在觀察系統中的滯後。讀取和寫入文件需要大量時間。此外，我的文件系統有時會變為只讀（顯示只讀文件系統，無法執行操作）。

我有大量的資源（12GB RAM 和 i3 第 7 代）。

我應該採取什麼步驟來恢復這些東西？

是的，您的驅動器出現故障：

5 Reallocated_Sector_Ct   0x0033   001   001   005    Pre-fail  Always   FAILING_NOW 9800

您無法做任何事情來使驅動器“變得更好”。您接下來需要做什麼取決於您擁有哪些備份（如果有）。如果您沒有，請停止使用您的系統並獲得至少與筆記型電腦驅動器一樣大的外部驅動器，然後將盡可能多的筆記型電腦驅動器複製到其中（使用ddrescue）。
